European Union leaders have signed a security agreement with Ukraine, kicking off a two-day summit at which they will also set a strategic course for the EU for the next five years and appoint the people who will run the EU’s key institutions. Leaders of the 27 EU countries, meeting formally for the first time since European elections on June 6-9, gave a warm welcome to Ukrainian President Volodymyr Zelenskyy on Thursday, who made a rare personal appearance in Brussels for the signing ceremony.
